# Drone Attacks on Russian Infrastructure: Yandex's Second Data Center and Komi Oil Refinery Hit

## 🎯 Key Points

- Drones attacked Yandex's second data center in Kaluga, disabling server modules
- On October 8, a similar strike hit the company's largest data center in Ryazan Oblast
- The Ukhta Oil Refinery in the Komi Republic was targeted by a drone strike
- The Redkin Experimental Plant in Tver Oblast producing fuel components was attacked

In October 2026, Russian infrastructure once again came under a large-scale drone attack. The target included the second Yandex data center in recent times, located in Kaluga. According to the company's official data, several server modules were completely disabled as a result of the nighttime raid, which could potentially cause disruptions in the technological giant's key digital services.

### Chronology of Attacks on Digital Infrastructure

The attack on the Kaluga data center followed a similar incident on October 8, 2026. At that time, Yandex's largest data center in Sasovo, Ryazan Oblast, housing the company's powerful supercomputers, was targeted by drones. Following that fire, users across Russia massively complained about global disruptions in search, transport, and cloud services. The new attack in Kaluga worsens the company's technical crisis, although Yandex representatives assure that there are no casualties among the staff and emergency services are already dealing with the aftermath.

### Strikes on the Fuel Sector and Industrial Facilities

In addition to digital infrastructure, drones attacked oil refining and chemical industry enterprises in several Russian regions. For instance, a strike was recorded on the Ukhta Oil Refinery in the Komi Republic, which processes about 4.2 million tons of oil annually. Simultaneously, on the night of October 9, 2026, the Redkin Experimental Plant in Tver Oblast, which specializes in producing components for aviation fuel, diesel, and missile weapons, came under attack.

### Contradictory Data

Noticeable discrepancies in assessing the consequences of the nighttime raids can be observed between official government reports and corporate statements. Kaluga Oblast Governor Vladislav Shapsha reported nine civilians injured in the nighttime attack, but in his initial statement, he completely omitted the fact that the Yandex data center was destroyed. At the same time, the IT company's press service officially acknowledged the failure of several server modules, emphasizing that the scale of the damage is still being assessed.

### Expert Assessment and Long-Term Consequences

Military and economic analysts note a shift in attack tactics, which are now targeting not only the oil and gas sector but also the critical digital infrastructure of major technological monopolies. The failure of data centers providing supercomputing and cloud computing services deals a severe blow to the digital economy of the Russian Federation. Restoring specialized equipment will take months given technological limitations and sanctions pressure.
